This is perfect for adjusting the air in my sport bike. It’s simple to use, accurate (when comparing readings with a $20+ digital tire pressure gauge) and fast. I increased the pressure by a couple of pounds and it took seconds. I like that it shuts itself off when reaching the correct pressure. The quality seems to be great. It is loud, just like every other air compressor I’ve ever used. It’s definitely worth the money.

I’ve been looking for a portable tire air pressure, as I was getting tired on paying $1.50 in quarters at the gas station. This portable tire pressure air compressor allows me to have it on the go or use at home. It plugs into the car’s cig lighter. The compressor then draws it’s power from your car, and you connect it via tube to the tire (bicycle or car). It also comes with various nozzles for ball pumping as well. Once powered on, you can set it to the desired setting (automobile, bicycle) and then press long press the power button. It will begin compressing air into the tire and you will be able to see the psi increasing. I tried this on my electric bicycle which requires 25-30 psi and it went from 18-25 in seconds. The added light at the top is great when you can’t see due to shadows or dim lighting.

I love this compressor! I use it all the time to fill my tractor tire that keeps deflating. I also used it to inflate my car tire and the tractor tire the same afternoon, and it still shows 3 fully charged bars. I also used it to inflate a large swim float. I wouldn't be without it. I also ordered one for my son to take on his road trips as he travels a lot.
